按特定顺序运行测试

Question

I've installed in Visual Studio 2013 the Google Test runner extension.

Now I have a test project

TestProject
    |
    |-InitializationTests.cpp
    |-RunningTests.cpp

I want to run all test cases inside InitializationTests.cpp before tests inside RunnintTests.cpp . How can I accomplish this?

Answer 1

Sure You Can! It's a program not concrete.
main.cpp:

::testing::GTEST_FLAG(filter) = "tA.*";  
RUN_ALL_TESTS();  
::testing::GTEST_FLAG(filter) = "tB.*";  
RUN_ALL_TESTS();  
::testing::GTEST_FLAG(filter) = "tC.*";  
return RUN_ALL_TESTS();  

It will run in the next order:

 tA.*,   
 tB.*,  
 tC.*,  

Answer 2

Test framework normally do not allow to control the order of tests, because it is a general requirement that tests are independant from each other.

But you can always run a single test, and Google Test has a powerful option to control which tests are to be run. From Google Test advanced guide : If you set the GTEST_FILTER environment variable or the --gtest_filter flag to a filter string, Google Test will only run the tests whose full names (in the form of TestCaseName.TestName) match the filter

For your use case, supposing you execute all tests in your test project by calling :

TestProject

you could run only initialization tests by running :

TestProject --gtest_filter=InitializationTests.*

(provided InitialisationTests.cpp contains tests for test case InitializationTests )

Answer 3

Tests order should be independent. And GTest does not allow to control the order. Even more: tests can be run in parallel
